The traditions of today are the legacy of the past, as mediated by both change, continuity, and deliberate re-invention.

The traditions of tomorrow may in the same way be the legacy of today and the past that has led up to it; we won't know, though, until it happens.

Our ancestors are mostly dead, and unlikely to be in a position to learn much from us. Our descendants, on the other hand, may inherit some sort of tradition from us. It will depend on whether or not we leave them anything worth having.
